The ring 5 maybe forged, but preferablyconsists of g. 18 'is a fragmentary! section. on the line 15 sertion ofa plug or other fltting into the'ring or its removal therefrom.

In the form of construction shown in Figs. 1*

to 16, inclusive, the interlocking devices comprise metal sections 1lying flat on the inner face of the flange and integrally connectedattheir outer ends to the edge or periphery of the flange I. In providingthe sections. 1 in this form of construction, the ring may be blankedfrom a.

sheet metal with extensions 1, as shown-in Fig. 4. These extensions maybe uniformly spaced around the periphery of the flange, as shown in Fig.4,

or disposedin any other spaced relation, such as shown in Fig. 8a; thislatter-arrangement insuring a. more economical use offthe metal sheetfrom which the ring blanks a' re"stamped.

Where the plug is to be sealed against tampering, the sealing means mayrequire two .ior more of the extensions to bear a predeterminedrelation, such as shown,for example, in Fig; 1011 The extensions I arerelatively narrow and preferably provided with parallel sides "and ofless length than the width of the flange 6 at either side of the body 5,for a purpose which will later appear. The extensions I are foldedoveronthe inner surface of the flange 6, as shown in Figs. 5, "1 and 8,to form the interlocking elements or devices 1 on the flange within itsperiphery. The ring 4 may then be' inserted into a suitable: sizingmachine to make the periphery of the flange, particularly throughout theportions, adjacent the folded extensions I, concentric to the axis ofthe ring, to facilitate theseatingof the flange in its seat (laterreferred to) in the wall'orjheadi;

The head a is formed with an openingfhavin'g a laterally extending. neck8, and around the neck 8 the adjacent portion of the head 3 is em:bossed to form depressions or pockets I'll, which receive theinterlocking elements 1.] In the preferred arrangement, the metalwal l,;l around the neck 8 is embossed to form an annular seat 9 for the ringflange 0 and the bottom wall of the seat 9 is embossed to form thepockets ill. In assembly, (a) a gasket it ismounted on, the flange 6between the ring neck Sand inner. ends of the elementsv I, (b) the ringneck or body 5 extends into and through .the ne'ck'B, (c) the flange 6fits into the embossed seat .9, (d), the interlocking elements 1 fltinto the pockets Ill and (e) the circumferential free'or outer end ofthe ring neck 5, which vis reduced in thickness,

, is bentor curled over the circumferential'free end of the neck 8, asshown at l2, thereby's'ecuring the flange 6 in its seat with theelements or the devices I seatedin their respective embossments orpockets III. The pockets III are complementary in shape, size andarrangement to the elements I and due to the engagement of'each element1 with the side walls of the adjacent pocket, the ring 4 is heldagainstturningor looseness. As the sidewalls of the pockets III areintegral with their. inner and outer endwalls and bottom walls,,they areadequately reinforced to resist strains resulting from the tightening orloosening of a plug, one form of whichis indicated as an entirety at [3,in the body or neck 5.

' amassa Any desired construction of plug may be used,

that shown being of novel form; but no claim is made thereto as it formsthe subject-matter of my co-pending application Ser. No. 699,757, PatentNo. 2,024,029. The gasket II is preferably formed of rubber and ifdesired it may have a widthslightly greater than the distance betweenthe ring neck 5 and inner ends of the elements I.

In this arrangement the gasket I I may be assembled on the flange andfrictionally held thereon in position. This assembly can be made by thering maker and thus eliminate separate handling of the gaskets inmounting the rings on container heads.

If desired, the' side walls of the extensions I may converge inanoutward direction, the convergence being such that whentheextensionsare disposed in their folded positions, their side wallswill be onimaginary radii of the ring. In

;this arrangement the side walls of the pockets or embossments ill willbe correspondingly shaped and arranged.

Fig, 3 shows the ring 4 mounted inthe head or wall :in an invertedposition and arranged to provide a flush inner surface to insurecomplete drainageofthe container. When the ring is ,mounted in thismanner, a sealing cap I! of thin sheet metal may be applied by bendingthe side wall I! of the cap inwardly around the shoulder resulting fromthe curled portion i2. When a sealing cap is used I prefer to provide agasket it between it andthe'plug i3 and curled end xii, asshownin Fig,42.

Fig.9 shows the ring [mounted in the head 3 with its neck 5' dependinginto the container, with the 'embossments in' the head so arranged that'the outerlface of the flange 8 is in the'plane of mounted in thisposition, the construction adapts itself to varying types of sealingdevices.v For example, two extensions I may be folded against the innerface "ofithe flange 6, (see dotted lines in Fig. 10) and thefothertwoextensions left in an extended position'bu't slightly bent upwardly attheir outer ends (as shown at 11;) and formed with openingsto serve'assealing devices (either or both) fortheatt'achment of a" sealing means(not shown) V Anotherfform ,of' sealing device consists in placing abendable section I6 of thin .the walls of its 'seat.= Another form ofsealing device consists in assembling a bendable section l1 of thinmetalwith one or more devices I with its inner end clamped between it and theflange, the section extendingradially'of the ri'ngand beyond its flange(see Figs. 15 and 16); inthis arrangement the section. II is also.clamped between the flange 6 and the walls of its seat. In the formsofconstructionshown in Figs. 12 to 16, inclusive, the sealing device orelement is secured to the ring by the folding over of,theadjacentextension I and becomes a part thereof so that separatehandling of the device in mounting the ring is not required; also, suchmounting does not require a special set of dies, as the sealing devicesconform to the flange wall and the seat .walls when the ring isinserted'in position and aisaeaa pressure is applied to secure itin'flnal position in the container wall. I

Referring to Figs. V1'! to 41, inclusive, the inter V locking devicescomprise sections it which are 19 and-20, the section It is bentupwardly substantially perpendicularly 'to the face of the flange, asshown at l9, and then laterally to dispose its end portion above andparallel to the flange 6, as shown at 20. As shown in Figs. 17 and 18,the embossments ID are arranged and shaped to receive the sections--l 8.In this form of construction each two adjacent slits a extend parallelto a radius of the bung ring and each slit b connects the inner ends ofthe adjacent slits a.

In Figs. 21,22, 23 and 24, the slits a, b, are disposed similar to thearrangement of the slits shown in Figs. 1'7, 18, 19 and 20, but themetal section is bent upwardly so as to lie in aninclined position.whereby portions of its side walls extend above the inner flange face toprovide the inter-,

locking devices. In Figs. 25, 26, 27 and 28, each slit b connects theouter ends of the slits a, so that the metal section is connectedintegrally at its inner end to the flange 8 and is inclined up wardlysothat its outer end is disposed above the'inner flange face.

In Figs. 29, 30, 30a, 31 and 32, the parallel slits a extendsubstantially tangentially to imaginary circles concentric to thebungring axis and each slit b extends substantially radially of saidaxis, the resulting metal sections it being inclined relative to theflange so as to project above its inner face to provide the interlockingdevices.

In this embodiment of the invention, each set of slits a, b, ispreferably arranged in reverse relation to adjacent sets of'slits, sothat the free ends l8 of alternate sections l8 will be in position toresist rotative forces in one direction and the remaining sections willbe in position to resist rotative forces in the opposite direction.

In Figs. 33, 34, 35, 36 and 37, the slits a, b, are shown disclosed inthe same relation as the slits shown in Figs. 29, 30, 30a, 31 and 32,but the metal section It is bent up and disposed perpendicularly to theflange 8. Inthis form of construction, the slits a are shorter thancorresponding slits in the previously described forms, as the section l8extends in the perpendicular direction but a short distance, no greaterthan its thickness.

In Figs. 38, 39, 40 and 41 I show another embodiment of the invention,wherein the interlocking devices comprise sections of the flange 6 upsetrelative to the flange in parallel relation thereto; that is, the metalof the flange is scored part way therethrough on all four sides of eachdevice and the resulting section is stamped or displaced laterally, sothat the device projects beyond the inner face of the flange.

In each form of construction, the metal wall 3 is embossed toaccommodate the shape, size and arrangement of the projectinginterlocking devices, in complementary relation thereto, to insure aninterlock therewith.

In the embodiments herein disclosed, the metal I wall may be suitablyembossed to was; projecting devicesor both, the flange and deviceswithout imposing undue strains' on 'such wail. Accordingly, danger ofthemetal cracking. during shaping of the wall, with resulting repairs orleakage, is reducedto a minimum.
